Cecilia is a graphic user interface for the sound synthesis and sound processing package CSound. Cecilia enables the user to quickly build graphic interfaces with sliders and curves to control CSound intruments. It is also an editor to CSound with syntax highlighting and a built-in reference.
GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like DPX, DICOM, BMP, GIF, JPEG, JPEG-2000, PDF, PNG, PNM, SVG, and TIFF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X.
TkLife is a multipurpose artistic program designed to manipulate 64 different colors on a canvas. It can be used to automatically generate complex patterns simulating the birth, life, and death of cells. It can be used as a simple drawing tool. In BioMode, it can be used to visualize and analyze multiple DNA sequence alignments. It can also be used to visualize numeric data from tab-delimited spreadsheets.
SndBite is a specialized audio editor designed for breaking large recordings into smaller components with great efficiency. Its principal intended application is in linguistic research where it is often desirable to put each word or sentence into a separate file before further processing. It is also useful for measuring pause durations. Its features include multiple simultaneous views of the waveform at different resolutions, the ability to position window edges at transitions between sound and silence, automated setting of cut points at zero-crossings, automatic filename generation easily controlled by the user, and optional automatic playback on window motion. It is scriptable and may be run in batch mode without the GUI.
ColorExplorer is a tool for exploring the color space and finding out how colors, color names, and numerical color specifications are related. The user can specify a color by selecting its name from a list of color names, by adjusting sliders that control the mixture of red, green, and blue, by entering a numerical color specification, by copying it from the history list or elsewhere on the display, or by requesting a random color. The numerical specification of the current color and an example of that color are shown in a pair of adjacent boxes. The color name list may be searched by entering a regular expression or by requesting the closest match to the current color.
